No, openSUSE 10.3 has no built-in provision for AIGLX support. In fact, I don't think the version of compiz that comes with 10.3 will even support it, that was added by the community via beryl, and then remerged in as part of compiz-fusion but you'll need to use the openSUSE build service to obtain the updated packages.

The openSUSE wiki has fairly detailed step by step info if you're looking at using compiz-fusion.
